DRAFTING TABLE.

Application filed June 1, 1923, Serial No. 642,756. Renewed November 9,1926.

The principal object of the present invention is to provide a firm .andrigid table for securely .holding drafting boards of comparatively largesize and such as are used in architects, engineers and other oflices.An-

other object of the invention is to provide a drafting table possessedof the advantages above mentioned and of which the construction iscomparatively simple and inexpensive yet very rigid, solid, durable andconvenient.

Other objects of the invention will appear from the followingdescription and the in vention may be generally stated to be embodied ina drafting table comprising in combination, a tubular metallic legstructure, and metallic top rails constituting a stand, and metallic endand side bars constituting a swinging frame pivoted to one of the toprails, and means for adjusting the swinging frame at variousinclinations to the stand.

The invention also comprises the improvements tobe presently describedand finally claimed.

In the following description reference will be made to the accompanyingdrawings forming part hereof and in which- Figure 1 is a perspectiveview of a drafting table embodying features of the invention.

Fig. 2 is a transverse sectional view of a part of the table drawn to anenlarged scale, and

Fig. 3 is a view, partly in elevation and partly in section, showingsome of the parts detached.

In the drawin s 1 are tubular metallic legs, and 2 are tu ular metallicbraces, and is a tubular metallic top rail, and 4 are metallic top railsof channel section, and these parts constitute a stand. 5 .are metallicside rails, and 6 is a metallic end rail, and 7 is an intermediate bar,and these parts constitute a swinging frame pivoted to the tubur lar toprail 3, and adapted to lie flush with the tops of the rails of channelsection. 8 is a hand lever pivoted to the intermediate bar 7. 9 is acatch turnable on the tubular top rail 3 and adapted to receive the handlever 8. 10 is a quadrant pivoted to the swinging frame and arranged toengage a locking bar 11 carried by the legs of the stand. 12 is a springfor holding the toothed quadrant 10 up to the bar 1].. 18 are spurs orprojections extending upward. from the stand. and from the swingingframe for holding a drawing board. The stand and swinging frame areshown as pivotally connected by bending the ends of the side pieces ofthe frame around the top rail 3. The catch 9, while free to turn on thetop rail 3, is held against end motion by collars 1-3.

Normally the hand lever 8 occupies the position shown in dotted lines ata, and in order to tilt the swinging frame the hand lever 8 is turnedabout its pivot 14 into engagement with the catch 9, as shown in fulllines, and then by bearing down on the handle of the lever 8the latterturning with the catch 9 as a fulcrum affords a means for lifting theswinging frame to the required inclination in which osition it can beheld by the toothed qua rants. By the same means the frame can belowered flush with the top of the stand. The metallic parts may beconnected by brazing and they are very firm and rigid yet not undulyheavy. The drafting table affords a solid support for a drawing boardwhich can be easily made horizontal or inclined.

It will be obvious to those skilled in the art to which the inventionrelates that modifications may be made in details of construction andarrangement without departing from the spirit of the invention which isnot limited as to those matters or otherwise than as the prior art andthe appended. claims bination tubular metallic legs and tubular metallicbraces and a tubular metallic top rail and metallic top rails of channelsection constituting a stand, metallic side and end and intermediatebars constituting a swinging frame pivoted to the tubular top rail andadapted, to lie flush with the top rails of channel. section, a handlever pivoted to the intermediate bar, a turnable catch on the top railadapted to receive the hand lever, 10 and 'a normally engaging toothedquadrant and locking bar between the stand and frame.
